LOCKING DEVICE ron nnawnns.

To all whom it may concern .Be it known that I, JOHN'S. KRAMER, asubject of Austria-Hungary, residing at Steger, in the county of Willand State of Illinois, have invented new and useful Improvements inLooking Devices for Drawers, of which the following is a specification.

This invention relates to bureaus, dressers and other similar articlesof furniture, and its object is to provide a novel and improvedarrangement of drawers and means for locking the saine. I

The objects stated "are attained by means of a combinationandarrangement of parts to be hereinafter described and claimed, and

- in order that thesame may be better understood, reference is had tothe accompanying drawings, forming a part of this specification. 7 I

In the drawings, Figure 1 is. a perspective view of th bureau; U

Fig. 2-is a central cross-section thereof; Fig. 8- is a cross-sectiontaken adjacent to one end of the bureau, with certain drawers omitted;

Fig. 4 is a perspective view of a drawer lock; o p

' Fig. 5is a plan view of one of thedrawers; Fig. 6 is a perspectiveView, partly broken away, of 'a drawer or slide associated with thedrawer shown in Fig. 5;

Fig.7 is a perspective view, partly broken away, of the drawer shown inFig. 5, with the slide of Fig. 6- omitted;

Fig. 8 is adetail in perspective of certain parts of the drawer lock;

Fig. 9 is a detail in'perspective showing another drawer lock, and IFig. 10 is a perspective view of a drawer controlling said lock.

Referring specifically to the drawings, the frame of the structurecomprises a back 1,

end walls 2, a top 3 and corner posts 4 which extend for a shortdistance below the bottom of the structure to serve as supporting legs.

The design of the structure is such that it has.

the general appearance of a bureau or dresser. I g I On the top 3, atthe ends thereof, are drawers 5 .and 5 which are housed in casings 6 and6 and the't'op in the space between these casings serves as theinstrument board of a talking-machine shown diagrammatically in Fig.2. Alid or coverclosing down on the top 3 and over the tone arm 7 andturntable Specification of Letters Patent. 7

8 of the tal-kingmachine is shown at 9. The

Patented Sept.14, 1920. Application filed. June 23, 1919; SerialIva-305,224..

horn 10 of. the machine extends from the top i 3 down into a compartment11 closed in front by two doors 12 on the back of which may be mirrors.1

On opposite sides of the compartment 11,

between the latter-and the end walls 2, are

drawers 13, and below the compartment and the drawers are located twowide drawers 14 and 15 extending throughout the entire width of thebureau betweenthe end walls 2 thereof, and located'one above the other.

The following lockingmeans for the bottom drawers 14 and 15 are provided1 'In a dovetailed longitudinal slot 16 in'the bottom of'the drawer 5 isslidablymounted a block 17 carrying a. combination lock, the knobof'which is'shown at18 and the bolt at 19. That portion of the blockfrom which the bolt is to be projected is below the bot tom of thedrawer, and the "bolt moves in a direction transverse of the drawer. Thebolt is normally retracted flush with the side of the block, but whenapredetermined combination has been worked out, aturn of theknobprojects the bolt a certain distance; or,

a lesser distance if a different combination is used. I V The purpose ofthe bolt 19'is to depress a pair of cams 20' pivoted at 21 in a recess22 in the top3 beneath the bottom of the drawer 5'. -Each cam 20 isconnected toa downwardly extending rod 23 connected to one end of alever24, to the other end'of which latter is connected a rod 25. Thelever 24 is fulcrumed to one of theend-walls 2, as shown at 26, and to asuitable support 27 on theback or rear walll is fulcrumed'alever28 toone end of which the rod 25 is connected; The other end of the lever 28is connected to a spring latch 29. Onelatch is provided for thedrawerzl4 and another latch for the drawer 15, with a cam 20 andtheconnections 7 hereinbefore described foreach latch sothat the drawersmaybe independently locked one. VVhich cam is to be depressed willdepend on the extent to which the bolt is projected, and as one ofthecams controls the I lock of one ofthe drawers, and the other drawerlock is controlledby the other cam, the 'locks are independentlycontrolled.

When the cams are depressed the rods23 swing the levers 24 and thelatter, through the rods 25, operate the levers 28 to depress thelatches 29 to which the latter are connected. The latches are normallypositioned in front of the downwardly extended rear walls of thedrawers, in which position of the'latches, the drawers'are held locked,but

- when the latches are forced down clear of nected to the levers 24.

The end walls'2 of the bureau have roller bearing supporting moldings 31for facilitating movement of the drawers 14 and '15, and also ribs 32which slidably fit in grooves 33 in the sides of said drawers to keepthe latter from rising when slid in and out. The rods 23 are adjustablyconnected to the levers 24 by clamp sleeves 34 soas to make the actionofthe locking mechanism accurate.

Referring, now to Figs. 5to 8, the small top drawer 5 has its-rear endopen, and its side walls have slide ribs. 36 to guide a slide or falsedrawer 37 having grooves 38 in which the ribs seat. When this doubledrawer is opened, all. that is visible is the false drawer 37, whichlatter hastwo compartments 39- for small articles wanted handy. Thecompartments are of different depths to clear certain mechanism in thedrawer 5.

I In order that the false drawer 37 may always be. in front .and readilyaccessible, it is held in such position by a'spring latch 40 accessiblethrough an opening 40 in an inclined wall 41 and acting on a keeper 42on the inner faceof the front of the drawer 5. Whenthe false drawer isto be moved back, thelatch is released, and then the drawer isautomatically drawn back by a 5 spring 43 acting on a slide bolt 44which is held back by. aestop plate 45. When the drawer 37 ispulledforward and closed, the spring 43is placed under'tension.

The drawer 37,'when closed, conceals the knob 18 of the locking devicehereinbefore described, and the knob is therefore not accessible untilthe drawer is slid'back to uncover the same. The floor molding' 47 shownin Fig. 8 is designed to keep the drawer 5 elevated to the proper heightfor the operation ofthe block 17 Figs. 9 and 10 show a device thatordinarily prevents the drawers 14 and 15 from 7 being pulled entirelyout of the bureau, and

. yet permitting this when the top drawer 5 is drawn out. The floor'ofthe casing 6 inclosing the drawer 5 supports a downwardly extendingvertical rock shaft 50 having at its upper end a laterally projectingcam arm 51. A spring 52 connected to the shaft 50 tends to turn it in adirection to hold the cam arm 51 as shownin Fig. 9. The drawer 14 (aswell as the drawer 15) has a side groove 53 into which a side pin- 54carried by the rock shaft 50 projects when the latter is given .apartial turn.

Vith the parts as shown .in Fig. 9, the drawer 5 being removed, thedrawer 14 may be inserted or removed, but when the drawer 5 is insertedinto its casing 6, a cam- 55 on the bottom of said drawer (see Fig.

10) engages the cam arm 51 and rocks the shaft 50 so that the pin 54enters the groove 53, thereby. preventing removal, of the drawer 14. Itwill be understood-that the locking the drawer 15. V

The block 17 is provided with a handle 46 for the manipulation thereof.

Below the compartment llthe bureau shaft 50 has another pin lower downfor may be-fitted with a concealed shelf 56,

which when drawn out affords a handy place for toilet articles orpreparations.

I claim: 7 r
